Recently, checking material, I found that many interesting phenomenon. Especialy, there are a lot of tricks in a dryer.

For example, coal dryer have many names.

Such as coal, coke, the lignite, type coal, fly ash and drying equipment. And mine kind, such as mining, slag, etc. Drum dryer, drum dryer, the three-cylinder dryer, double barrel dryer, actually are is for roller said. Drum dryer is not drum dryer Similar rotates the dryer is used in cement; slag drier is back to the transformation. And sand dryer, river sand dryer, turning the dryer, quartz sand dryer is not same? According to the application field Industrial dryer, cardboard, yeast, vinasse, desulfurization gypsum, cement, other not say anymore. Agricultural dryer, corn skin, food, bean dregs, sweet potatoes slag, also not say anymore. Sludge, slag, coal slime also seems to guess, is all waste residue waste, in the same kind of dryer is probably work.

Dryer style

Vertical, horizontal, the net belt, tunnel type

According to the material characteristics such as high humidity the dryer

Energy saving the dryer, as if no one enterprise but themselves not saving energy, environmental protection and efficient, if possible it should also said he is low carbon?

Also good for the dryer on baidu encyclopedia classification and development history has more detailed introduction, I will be the main essential parts of therapies as follows to share with you.

The development of the dryer and classification

First came the intermittent operation of the fixed bed dryer. The middle of the s, DongDao drying machine, continuous operation of the direction of development. Rotary cylinder dryer is achieved the particle materials agitation, dry ability and strength can be improved. Some industry development to adapt to the industry respectively the continuous operation requirements of the drying machine, such as textile, papermaking industry drum drying machine.

Of the 20 th century, dairy production began to use spray drying machine, liquid materials for large-scale dry provides a powerful tool. 40 s, along with the development of the fluidization technique, high strength, high productivity FeiTengChuang and streaming dryer arise. And freeze sublimation, radiation and dielectric drying machine is to meet the special requirements to provide a new way. 60 s development the far infrared and microwave drying machine.

classification

According to the operation pressure can be divided into normal pressure and reduced pressure (pressure dry machine also called vacuum drying machine). In the vacuum operation can reduce wet points boiling point and material the drying temperature, steam not easy leaked out, and so, vacuum drying machine is suitable for drying of material, easy oxidation, explosive and poisonous material and wet points to the occasion of steam recovery.

According to the operation method can be divided into intermittent and successive.

According to dry medium can be divided into the air, black or other dry medium. Such as hot air stove, black, producer gas generator, etc

According to sports (material mobile and dry medium flow) way can be divided into and flow, countercurrent flow and wrong.

According to the heating mode, drying machine, the conduction of streaming into type, FuSheShi, dielectric type type etc.

Drying equipment common sense: common type of dryer in our country are common spray dryer, and the air is dry machine, fluidized bed drier, braising drying machine, fluidized bed drier, such as spray granulation. Braising drying machine of the spray drying is drying equipment one of the most advanced equipment.

At present, there are a lot of businessmen can provide this type of equipment.
